When the shaftB 0 formed therein the bearings A and A in is revolved by the pulley O, the crank-pin B which is mounted the shaft B, having secured will rock the tool-carrier H about its fulcrum thereon the pulley O and hand-wheel D. The thus producing a reciprocating movement of bearings A and A are lined with composithe burnishing or finishing tool K, which is 5 tion-bushings fixed therein, the bushing A very effective in its Work, the springs J J of the hearing A projecting beyond the outer serving as yielding stops or cushions to check end of said bearing and having adjustably the momentum of the vibrating carrier and secured thereon by the clamping-bolt E the assist in reversing its motion with the minihub F, having an outwardly-projecting arm mum of shock or jar. By this construction 50 F formed thereon. The arm F may be forked the mechanism is greatly simplified, and the number of wearing parts are so reduced that there is less liability of the machine. getting out of order, which has heretofore been the case when the operating-tool has been driven at a high rate of speed.

What we claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a machine-for finishing boot and shoe heels, the combination of a revolving. shaft, an outwardly-extending arm secured to the head, a tool-carrier fulcrumed upon saidarm near its outer end, an operating-tool mounted in the outer or free end of said carrier, a crankpin set in said shaft and connected to said carrier and adapted to produce a vibratory movement of said carrier about its fulcrum,

sidesof said fulcrum-bearing surfaces and adapted. to hold said carrier upon its fulcrum. and to serve as cushions to check the motion of said carrier in one direction andto assist in reversing its motion, thereby lessening the shock of the vibrations of the toolcarrier. i

2. In av machine for finishing boot and shoe heels, the combination of a revolving shaft, an outwardly-extending arm secured to'the head, a. tool-carrier provided at one end with a tool-holding socket and connected at its other end to said arm by V-shaped male and female bearing-surfaces,a pair of springs arranged. upon opposite sides of said fulcrumbearing surfaces and adapted to hold said bearing-surfaces in contact with each other, therebyforming a fulcrum. about which said carrier may bevibrated against the tension of said springs, an operating-tool mounted in said socket in said carrier, a crank-pinv set in said revolving shaft, and a rod connecting said pin and said carrier, whereby the revolution,

of said shaft will produce a vibratory movement of said carrier.

3. In a machine for finishing boot and shoe heels, the combination of a revolving shaft, an outwardly-extending arm secured to the head, a. tool-carrier provided at one end with a tool-holding socket and connected at its other end to said arm by V-shaped male and female bearing-surfaces, a steel pin reinforcing the bearing-edge-of the male bearing-surface, a pair of springs arranged upon opposite sides of said fulcrum-bearing surfaces and adapted to hold. said bearing-surfaces in contact with eachother, thereby forming a fulcrum about which said carrier may be vibrated against the tension of said springs, an operating-tool mounted in said socket in said carrier, a crankpin set in said revolving shaft, and a rod or link connecting said pin and said carrier, whereby the revolution of said shaft will produce a vibratory movement of said carrier.

4. In a machine for finishing boot and shoe heels, the combination of a revolving shaft,

.stops 'ment of said tool-carrier, mounted in said socket, a crank-pin set in an outwardly-extending arm secured to the head, a tool-carrier provided at one end with 'a suitable tool-holding socket provided with an opening opposite the end of said shaft and connected at its other end to said arm by shaped male and female bearin -surfaces, a pair of springs arranged upon opposite sides of said fulcru m-bearing surfaces and adapted to hold said V-shapedbearing-su rfaces in contact with each other and to serve as yielding or cushions during the vibratory movea finishing-tool said revolving shaft and extending through the opening in said tool-carrier, and a rod connecting said pinwith said carrier. and a pair of springs arranged upon opposite l 5. In a machine for finishing boot and shoe heels, the combination of a revolving shaft mounted in suitably-fixed bearings, a crankpin set in or carried by said shaf an outwardly-projecting arm mounted upon and 'adjustableabout one of. said bearings, a toolcarrier fulcrumed at one end to the movable endof said arm and provided with a socket at its other end,springs arranged upon opposite sides of saidfulcrum and adapted to serve as cushions to relieve the shock of the reversal of the motion, an operating-tool mounted in said socket, and a link connecting said toolcarrier to said crank-pin, whereby the rotation of said shaft will cause a vibratory move- ,ment of said carrier-arm and operating-tool I vertically, horizontally, or at any desired an- Igle,.according to the. position to which. said carrier-supporting arm is adjusted about the j axis of said shaft,

6. In a machine for fi'nishingboot and shoe heels, the combination of a revolving shaft,

a. crank-pin set therein, an outwardly-extendi'ngarm-adjustably secured about the bearing for said shaft at any desired. angle and provided near-its outer end with a V-shaped rib or projection and two inwardly-projecting studs, each having a nut, head, or shoulder at its inner end, a tool-carrier provided with a central opening to permit the free movement of said crank-pin and also provided at one end with a V-shaped bearing-surface and suitable slotted ears surrounding said studs, a spring interposed between the nut or shoulder of each of said studs and one of said I ears, an operating-tool secured to the end of said carrier farthest from its pivotal connection, and a rod connecting said crank-pin with said carrier.
